A dying 11-year-old boy with a love for motor sports has asked for racing stickers to decorate his casket after he made the heartbreaking decision to forgo his cancer treatments.

In February 2017, Caleb Hammond was diagnosed with acute lymphoblastic leukemia and spent the next year-and-a-half in and out of hospital as he underwent several rounds of chemotherapy and a bone marrow transplant. The young boy from Oskaloosa, Iowa suffered symptoms of heart failure and was in a medically induced coma for a week during treatment, set up by his family.

After a brief respite, an aggressive form of Caleb鈥檚 cancer returned in May. The family said he underwent another bone marrow transplant and more chemotherapy. After he failed to respond to those treatments, Caleb鈥檚 family said he made the decision to stop them and return home.
